When i was younger I saw an experiment on Mr wizards world(My idol, recently passed) where he took
aluminum foil, placed it in a pot of I think it was sodium bicarbonate dissolved in hot water on a stoveHe used a tarnished spoon and touched it to the Al foil and the tarnish dissappearedIthink this is how it went but Im not sureIt has been many yearsDoes anyone know or remember???Tarnish Removal from Silver Materials: -a tarnished piece of silver -a pan or dish large enough to completely immerse the silver in -
aluminum foil to cover the bottom of the pan (Note, these two materials can be combined by using a disposable aluminum pan) -enough water to fill the pan a kettle to heat the water (and oven mitts if you plan to move the pan) -baking soda, ~ 1 cup (depends on the amount of tarnished silver you have) Procedure: Line the bottom of the pan with
aluminum foil (or use your aluminum pan) Set the silver object on top of the
aluminum foil, making sure the silver touches the aluminum Heat the water to boiling, and pour it in the pan (be careful not to burn yourself), completely covering the silver Add baking soda (as needed); a good rule of thumb is ¼ cup per 1 liter.(Note, the mixture will froth a bit and may spill over; so you may want to put the pan in a sink – use oven mitts) The tarnish should begin to disappear quickly.You may need to let it sit, reheat the water, and/or add more baking soda if the silver is badly tarnishedOther related question
